"2a ze 24 27 INVENTOP `SAMUEL B. BEL/@LER ATTORNEY Patented Jan. 22, 1935 l UNITED STATES PATENT OFFICE STRIPEB Samuel B. Beugler, Los Angeles, Calif. ApplicatonSeptember 12, 1933, Serial No. 689,072 3 (Cl. Sil-62.6)

This invention has to do in a general way with the art of painting and is more particularly related to mechanical stripers, such as are used in painting lines or stripes on automobiles, furniture, and the like, for decorative purposes.

The general construction of a striper of this nature comprises: a barrel or tube adapted to contain the paint, such barrel having an end 'closure which is slotted for the 'reception of a In the operation of this tion of the arrow 4 in Fig. 2; and

rotatable wheel plate. device the paint or lacquer is placed in the barrel and the wheel is rotatedin engagement with the surface to be striped,l the paint-being car- "rled'by capillary or viscosity action along the periphery of the wheel which applies it to the surface.

All devices of this character, with which I am familiar, have an inherent defect in that part of the paint or lacquer is carried by the wheel beyond the point of'application, running down the face of the wheel as it traverses its upper course and being wiped olf the wheel by the top portion of the slot so that it drips onto the surface being striped.

Various attempts have been made to eradicate this defect, such as mounting a. packing or illter unit in the end of the barrel against which the wheel wipes, the object of such construction being to limit the amount of paint delivered to the Wheel. In another device, a compound system of wheels is employed. None of these devices has proved satisfactory.

It, therefore, becomes a primary object of this invention to produce a striping device of the class described in which the defect, above referred to, is entirely eliminated. This object I accomplish by forming the slot through which the wheel rotates in a manner such that all of the paint adhering to the wheel, after it has engaged the surface being striped, is carried back into the barrel. More specifically, therefore, my invention contemplates a novel type of slot formation whereby this objective canV be obtained. l

Since it is desirable in a striping device of this character to have a device which can be employed in forming strips of diierent widths, I propose to construct the device contemplated by this invention with a removable' closure cap which carries the striping wheel whereby a plurality of such caps having wheels of different widths can be employed with the same barrel. In this connection, it is still another object of this invention to provide a deviceAv of the class described with novel means for locking or holding the cap in place.

The details in the construction of a preferred form of my invention, together with other objects attending its production, will be best understood from the following description of the accompanying drawing which is chosen for illustrative purposes only and in which- Fig. 1 is a side elevation with parts broken away showing a preferred form of the invention;

Fig. 2 is an enlarged partial section further illustrating the construction of the cap or spring head contemplated by this invention;

Fig. 3 is a sectional elevation taken on the line 3 3 of Fig. 2;

Fig. 4 is an end elevation taken in the direc- Fig. 5 is a plan section taken on the line 5-5 of Fig. 4.

More particularly describing the invention, as herein illustrated, reference numeral 11 indicates a barrel or tube which has a closure 12 on one end through which a plunger `rod .13 slidably extends. The plunger rod 13 is provided With a plunger 14 within the barrel and has a button 15 on its outer end. Reference numeral 16 indicates an embossed portion formed on the top of the barrel, such portion being provided with a pair oi oppositely disposed slots 17 and 17', which are enlarged at their inner ends for the reception of guide bars 18 and 18. The guide bars are locked in the slots by means of thumb screws 19 and 19. It will be understood that various types of guide bars may be employed, depending upon the work in connection with which the device-is( used, the use of such guide bars being well known to those familiar with the art.

Reference numeral 20 indicates a cap or head which is shown as comprising al collar 21 tted over the open end of the barrel 14 and an end closure 22. 'I'he end closure plate 22 preferably made of appreciable thickness or, as shown, is provided with a forwardly 'extending lug -or boss 23 which has a downwardly extending projection 24. This projection 24 provides a convenient means for guiding the striper with an ordinary straight edge or ruler, and is an Vimportant and novel feature of the device contemplated by my invention. The cap or head 20 is provided in its-bottom portion witha slot, such slot having a portion 25 extending into the collar flange 21 and another portion 26 in the end closure, or, more specically, in the bottom portion of the boss 23.-:}'; [fle slot, which is formed by the slot portions 25and 26, just referred to, communicates lwith the interior of the barrel and contains a striping wheel plate 27 which is rotatably mounted in this slot upon a pin 28 which in turn is mounted in the lower'bifurcated end portion 24 of the boss 23. This wheel plate may be of any desired width, depending upon the width of strip desired and its periphery may be knurled as is well known' to those familiar with the art. The radius of the wheel, however, must be such that it has a segment the class. described so 2. extending through the two slot portions and 26 into the interior of the barrel.

For the purpose of admitting the segmentJ of the wheel extending into the barrel, as just pointed out, I provide the end of the barrel with a notch indicated at 30. In order that the paint Withdrawn from the barrel by the wheel during its rotation may be confined, as far as possible, to the edge of the wheel, I form the slotportion 25 in the collar flange 21 so that itssides are in substantial sliding engagement with the face of the wheel. The depth of this slot, however, is such that its inner end 3,1 is spaced a slight distance away from the periphery of the wheel. vThese two -features are best illustrated in Figs. 2, 3, and 5.` l

It was pointedvout above as the primary object of this invention-to form a head construction'of that all of the paint adheringto' the. wheel .after it has engaged the surface being'striped is carried by the wheel back intothe. barrel by the edges of the slot whereby the dripping -of paintonto the work, which occurs in the con-y ventionalstripery'is eliminated. IIhis is accomplished byforming the upper part of the slot portion 26 through which the wheel rotates in `passngninto. the barrel of a width and shape such that a substantial space surrounds both l the .edgeand the side surfaces of the wheel when it is rotating into the barrel. I have found that formost satisfactory operation it is important that the slot portion 26 be made substantially larger .at its outer edge 32 than it is at its inner edge=33 where the Wheel rotates into the barrel.

In other words, it is important that the wall of vthe slot diverge outwardly away from the inner edge or inner end 33 thereof. It is also important, as pointed out above, that the portion of the slot which is adjacent the lower half of the wheel, or adjacent that portion of the wheel l which is rotating away from the barrel, be in substantial sliding engagement with the side faces of the wheel, and it is therefore necessary that, in addition to diverging outwardly from the inner end 33, the slot portion 26 must also converge downwardly toward the axis ofthe wheel. The first feature mentioned above is best illustrated y in Figs. 2 and 5, and the lastimentioned feature is best illustrated in Fig. 4. 4

In addition to the slot construction just` de.- scribed, it has been previously pointed out that my invention also contemplates means for'frictionally holding the cap or head member on the barrel. This last mentioned means constitutes a spring finger 35 which is formed 'on the'end of the barrel by a short helical kerf 36.

In the operation of his device, the plunger 14 is Withdrawnto `thejdesired,point in the bar- I rel, thecap or head 2011; is remoyed, andV the-de-l sired quantityof paint or lacquer is poured into the barrel; 'A vstriping .head having a wheel of the de siredll` width is then placed over .the open end of the barrel; the plunger is pressed forward to bring the paint into slight pressure contact with the interior of the striping head; Guides of the desiredv type are thenjv set to the position re- .Fquired and the device is drawn along the object Vrto be striped so as to rotate the inside segment 0f the striping wheel downwardly out of instead of being wiped of!v acatar-rc the barrel. In this manner the paint is carried by capillary or viscosity action along the edge of the wheel and is applied to the surface `being striped. Any paint which adheres to the It is to be understood that, while I have here- .in described and illustrated one preferred form of my invention, the invention is not limited to Ithe precise construction described above but includes within its scope whatever changes fairly come within the spirit of the appended claims.

I claim as my invention:
